Final answer:
The proper technique for the power grip involves using the whole hand for a secure grip and lifting with palms facing the body, alongside correct body mechanics.
Step-by-step explanation:
The proper technique for using the power grip is to hold the handle with your entire hand, ensuring full contact with the palm and fingers, and wrapping the fingers around the object being held for a secure grip. Besides positioning your hands at the appropriate width apart, typically around 6 inches, you should make sure your palms are facing towards your body when you lift, which allows for maximum stability and force generation in lifting and handling tasks. The power grip is most effectively used in conjunction with proper body mechanics, involving the legs and core to minimize strain on the back and arms.
